1N4568E3

Single Zener Diodes Overview

The Microchip Technology 1N4568E3 is a temperature-compensated Zener reference diode with a nominal voltage of 6.4 V and a maximum voltage temperature coefficient of 0.001 %/°C. It operates at a test current of 0.5 mA, features a maximum reverse leakage current of 2 µA at 3 V, and has a dynamic impedance of 200 Ohms. The device is housed in a DO-7 (DO-204AA) glass axial-leaded package, supports an operating temperature range from -65°C to +175°C, and dissipates up to 500 mW.

Single Zener Diodes Feature Summary

• Temperature compensated design for minimal voltage change over broad operating ranges

• Flexible axial-leaded mounting terminals

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding low temperature drift
• Military qualification applications via JAN/JANTX prefixes

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' against official Microchip documentation to confirm lead-free compliance status, as standard datasheets may not explicitly detail environmental suffixes. Confirm package type and military qualification requirements if applicable. Cross-reference ordering codes with manufacturer catalogs to ensure correct revision levels.

Single Zener Diodes Selection Notes

Select this component when a 6.4 V reference with tight temperature stability is required. Compare the 0.001 %/°C coefficient against other series members like 1N4569A for lower drift or 1N4565A for higher current tolerance. Ensure the 0.5 mA test current aligns with circuit biasing constraints.

Single Zener Diodes Part Context

Part of the 1N4565 through 1N4584A-1 series of zero-TC reference diodes. These devices offer various temperature coefficients and test currents while maintaining a consistent 6.4 V nominal voltage. The series includes options for military qualifications and surface mount equivalents.

Single Zener Diodes Replacement Considerations

Direct substitutes include 1N4568A or JANTX1N4568A-1 for equivalent electrical performance. Verify package compatibility and qualification standards when replacing with variants from the same series.
